| Research Abstract |
This study first researched an efficient anonymous authentication technique based on elliptic curve pairing cryptography. Then, a network protocol based on the anonymous authentication was designed and its practicality was successfully examined. The result of this study will be applied to an advanced but complicated inter-organization network cooperation that requires anonymous authentication such as the wireless LAN roaming between universities.
